That's actually a huge relief, that reminder - I was thinking I'd lost the spare remote key for my 500, but now remember it came with a plain grey spare key like a Mk2 Punto key (but grey rather than blue). My 166 came with a spare remote key and an alarm with ultrasonic sensors. Fortunately it hasn't gone off yet, I hate false alarms...
Sorry to hear of the Mito break-in - in a 'good' area too.
Reminds me of a young couple I know (used to work with the guy) who lived together in a small rental house in the roughest part of Hamilton, car parked on the street. Houses around there often have broken windows and you see fights on the streets, but Pieter and Monique never had a problem.
Anyway after several years of double-income-no-kids, they bought an expensive new house in a new area on the north side of town. The house (I call it the concrete dungeon) is a modern industrialist style and even has central heating (unusual in NZ). Double garage but one night they left the car on the street for some reason and it was broken into quick as a flash. This is within a month of moving to the 'nice' area! I think the conclusion is that thieves aren't stupid - they know where the money is
